I did something similar, my BB are older boxes (4500 also a frame relay switch, a 7206 vxr with 12.1 ios) the only time I ran int problems with IPX was when I had to do the fast hellos on a bb router (the 4500 did not support that) and a weird scenario when I had to force MPLS to use passwords without using the MPLS neighbor password command, the 3745 I was using did not support the newer MPLS command, but I tested the command on my 7206 vxr with the later IOS just to see if I can see the commands. it worked just fine there.
The only problems I have and worry about is the hidden commands that you will not see in context sensitive help or see in the docs. I am concerned that will appear in the real lab. Anyone know what switch configs are not supported on the 3550 that are supported on the 3650? I have one 3750, one 4948, one 4510 and one 7613 in my lab that I use for switching, so far I have not run into anything that I could not do at layer 2 on those switches. I have had scenarios that I could not complete but they were related to routing.

I had 2x 3560's I got on the cheap, but didn't really wanna spend $2000 for another pair, so I got 2x 3550's for $220 and upgraded them to the ipservices image and I have been able complete almost all of the IPX labs that I have been through. Now the backbone routers are a different story. I'm sure I'll hear a few pitchforks coming my way by the time I finish this message, but I use a Juniper M10 split into very many VRF's which are broken out into dot1q trunks to simulate the 3 BB routers. I also have a spare 2610 (non XM) plugged in just in case I have a lab with a BB router that needs EIGRP, ODR, etc. Hey, it gets the job done :) -- max _______________________________________________ For more information regarding industry leading CCIE Lab training, please visit www.ipexpert.com Are you a CCNP or CCIE and looking for a job?
